Comment: howto secure virtual machines (Score 5, Informative) 51

by Euzechius (#30808566) Attached to: IEEE Ethernet Specs Could Soothe Data Center Ills

When using virtual machines you loose some control and visibility compared to the tradition pizza box server. A physical server is easy to pinpoint, easy to implement ACLs (ethernet/ip), Quality of Service, traffic monitoring or just to shut down a network port. :) Both VEPA and VN-link are technologies that allow you to better seperate different virtual machines on the same physical box.

For VMware, Cisco developed a virtual switch ( YES, a downloadable switch! :) that integrates with VMware ESX 4 that offers all this network security, monitoring goodness. This virtual switch is called the Nexus 1000v and can be downloaded at http://www.cisco.com/en/US/products/ps9902/index.html ( 60-day trial ).

About a year ago the ethernet specifications for data centers already got an extension called FCoE or Fibre Channel over Ethernet ( http://www.t11.org/fcoe ). Basically this allow you to use one ethernet network for both your lan and your storage san. And thus not needing to build out a seperate Fibre Channel SAN.

Should Gaming Worlds Join the Workplace? 68

destinyland writes "A Stanford professor argues that gaming worlds can keep workers engaged, and advocates elements of World of Warcraft or Second Life to hone workplace skills like teamwork, leadership, and data analysis. An IBM report also argues games like World of Warcraft teach leadership and that 'there is no reason to think the same cannot be done in corporate settings of various sizes.' The professor even suggests putting online gaming experiences into your resume. ('There's just so much that gets done [in a virtual world] that's just right on target with what happens in real business.') And Google's CEO also claims that multiplayer gaming also provides good career training, especially for technology careers. 'Everything in the future online is going to look like a multiplayer game. If I were 15 years old, that's what I would be doing right now... It teaches players to build a network, to use interactive skills and thinking.'"

THX Caught With Pants Down Over Lexicon Blu-ray Player 397

SchlimpyChicken writes "Lexicon and THX apparently attempted to pull a fast one on the consumer electronics industry, but got caught this week when a couple websites exposed the fact that the high-end electronics company put a nearly-unmodified $500 Oppo Blu-ray player into a new Lexicon chassis and was selling it for $3500. AV Rant broke the story first on its home theater podcast with some pics of the two players' internals. Audioholics.com then posted a full suite of pics and tested the players with an Audio Precision analyzer. Both showed identical analogue audio performance and both failed a couple of basic THX specifications. Audioholics also posted commentary from THX on the matter and noted that both companies appear to be in a mad scramble to hide the fact that the player was ever deemed THX certified."

We'll be following up when we have more information. We're answering this idea now because there are so many similar HTML5 ideas and we want to give other ideas a chance to be seen.' Now all the top ideas are concerning copyright and DMCA abuse."

Using EMP To Punch Holes In Steel 165

angrytuna writes "The Economist is running a story about a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, who've found a way to use an EMP device to shape and punch holes through steel. The process enjoys advantages over both lasers, which take more time to bore the hole (0.2 vs. 1.4 seconds), and by metal presses, which can leave burrs that must be removed by hand."

itwbennett writes "The IE attack code used in last month's attack on Google and 33 other companies was submitted for analysis Thursday on the Wepawet malware analysis Web site. One day after being made publicly available, it had been included in at least one hacking tool and could be seen in online attacks, according to Dave Marcus, director of security research and communications at McAfee. Marcus noted that the attack is very reliable on IE 6 running on Windows XP, and could possibly be modified to work on newer versions of IE."

A Space Cannon That Might Actually Work 432

from the whoooshing-sound dept.
Unequivocal writes "Chalk another one up to Jules Verne. Physicist John Hunter is proposing a space cannon with a new design idea: it's mostly submerged. 'Many engineers have toyed with the [space cannon] concept, but nobody has came up with an actual project that may work. Hunter's idea is simple: Build a cannon near the equator, submerged in the ocean, hooked to a floating rig ... A system like this will cut launch costs from $5,000 per pound to only $250 per pound. It won't launch people into space because of the excessive acceleration, but those guys at the ISS can use it to order pizza and real ice cream.' Though it won't work on people, with launch costs that low, who cares?"

Why Counter-Terrorism Is In Shambles 370

Posted by ScuttleMonkey
from the honest-guys-never-get-put-in-charge dept.
Early last week several questions were submitted to former CIA analyst Ray McGovern about the sad state of counter-terrorism in the United States, and he has answered frankly and in-depth. In addition, McGovern solicited former FBI attorney/special agent Coleen Rowley to review his answers and provide her own comments. Ray's biggest tip to the intelligence community was to "HOLD ACCOUNTABLE THOSE RESPONSIBLE. More 'reform' is the last thing we need. Sorry, but we DO have to look back. The most effective step would be to release the CIA Inspector General report on intelligence community performance prior to 9/11. That investigation was run by, and its report was prepared by an honest man, it turns out. It was immediately suppressed by then-Acting DCI John McLaughlin — another Tenet clone — and McLaughin's successors as director, Porter Goss, Michael Hayden, and now Leon Panetta."

ESA Wants ISS Extended To 2020 88

Posted by ScuttleMonkey
from the buy-two-at-twice-the-price dept.
Hugh Pickens writes "BBC reports that the European Space Agency's (ESA) Director General Jean-Jacques Dordain says that uncertainty is undermining the best use of the ISS and that only guaranteeing the ISS's longevity would cause more scientists to come forward to run experiments on the orbiting laboratory. 'I am convinced that stopping the station in 2015 would be a mistake because we cannot attract the best scientists if we are telling them today "you are welcome on the space station but you'd better be quick because in 2015 we close the shop,'' says Dordain. One of the biggest issues holding up an agreement on station-life extension is the human spaceflight review ordered by US President Barack Obama and the future of US participation in the ISS is intimately tied to the outcome of that review. Dordain says that no one partner in the ISS project could unilaterally call an end to the platform and that a meeting would be held in Japan later in the year where he hoped the partners could get some clarity going forward."

This attack would easily be prevented by the use of Private VLANs on your network. With PVLANs Clients connected to the LAN can only send Layer 2 frames to the default gateway and other pre-defined shared services such as printing, ad, mail, internet... Typically Private VLANs are very handy in shared/public environments such as hotels, public desktops.

Comment: Re:These look cool - but not for RAM (Score 5, Interesting) 93

by Euzechius (#28206895) Attached to: Cisco Introduces Rackmount Servers

I work for Cisco, so this post is biased.

If you want to know more about Intel Nehalem 55xx architecture.

It explains that a the server manufacturer using the Intel Nehalem 55xx processor can support up to 3, 6 or 9 DIMMs/socket. This corresponds with a memory bus speed of 1333, 1066 or 800Mhz. The latter is not often implemented and would give you (9x2x8GB) 144GB in a dual socket system.

What Cisco did is, developing a patented "memory switch" which presents up to 4 DIMMs as 1 to the processor, MULTIPLYING THE ALLOWED RAM TIMES FOUR. If the memory is running at 1066Mhz this gives you 48DIMMs. If the memory is running at 800Mhz this would allow up to 72 DIMMs in one server. The latter one has not been implemented.

Where would you ever need this kind of memory?

* Running VMware ESX, XenServer,... and assuming 3-4GB per VM -> imagine 96 VMs per physical box
* imagine running a 300GB MySQL database out of RAM without the need of a high end machine

Also the price per GB is not linear for memory. 8GB costs currently way more than 4x 2GB. So if you still don't need the 384GB memory, you can fill the 48DIMMs with 2GB and have a 96GB RAM server for a lower price.

There are also a lot of other features which are really different and better than the competition, such as centralized management per 320 servers. In more enterprise environments customers can also consolidate their SAN and their LAN network by using open standard FCoE.
